I9–14900KF Cooling

When it comes to cooling the 14900KF what is the best way to go?

Some examples
Air:
Zalman CNPS14X Duo Black
Noctua NH D15S

Liquid
360 MM AIO

Other PC parts that could be helpful:

SilverStone SEA1TB-G SETA ATX Black MidTower Case with
Tempered Glass
Gigabyte GV-N4080Super Gaming OC-16GD RTX4080S
16GB Graphics Card
Silverstone DA1000-GH Strider Gold 1000W Modular ATX
PSU

Thanks in advance

Re: I9–14900KF Cooling

360 MM AIO and you'll probably need to undervolt also.

Re: I9–14900KF Cooling

Apologies for delay in response thank you.

I am aware this question is nothing to do with cooling however I figured I would put it in here to save starting another thread in the hardware forum

I am currently running the following RAM:
XPG Lancer Blade 32GB (2*16GB) DDR5-6000 DIMM Black
Currently I am only getting 4553 MT/s. I have tried using the XMP settings to set at 6000 however my system doesn't want to start.
Would I see any gain if I was to change to
G.SKILL Trident Z5 RGB 32GB(2*32GB?

I have a
Gigabyte Z790 Aorus Elite X AX DDR5 ATX LGA1700 Motherboard

Reason why I have picked this particular RAM type is because according to Best RAM for the Intel Core i9-14900KF CPU the above memory I mentioned is the best for overclocking (article was last updated 1 February 2025) I'm also aware in the article they are only referring to 32 GB. I will be using 64.

Before building this machine I should have done more research regarding the memory

TIA for any advice

Re: I9–14900KF Cooling

Hi Speedy51,
I had a vaguely similar experience to yours when my DDR4 memory kit would not run at the advertised speed using XMP settings. I put this down to the fact that XMP is aimed more at Intel CPUs, and I was using Ryzen.
I later upgraded my Ryzen 2000 CPU to a Ryzen 3000 CPU and updated the BIOS. The same memory kit then worked perfectly at the advertised speed using the XMP settings.
I wonder, therefore, whether it would be worth trying a BIOS update before you give up on the XPG memory kit.
Since having the problem with this kit, I have always bought memory kits which are listed in the "Memory Support List" for the specific motherboard. (You can find this by locating your motherboard on the Gigabyte website, then going to "Support" and then "Memory Support List".)
In my (admittedly relatively limited) experience, kits on the relevant Memory Support List will work at the advertised speed without any trouble.
Hope this helps.
Cheers,
Mark

Re: I9–14900KF Cooling

Which XMP are you attempting to use?

I agree with what was said above.
1. Update BIOS
2. Check vendor list for approved ram modules

Fast ram does help with WCG work. It definitely speeds up runtimes for ARP1 but from what I have personally seen, the faster the RAM (using XMP or similar), the greater the chance of invalid ARP1 work units, even if the ram is running at its "rated" speeds.

Re: I9–14900KF Cooling

Thanks for your feedback Mark.

My system is Intel 14th generation. I am running the latest BIOS F6 released Sep 27, 2024 there is another one out however I believe it is Beta since it is is labelled F7B. released Dec 04, 2024 When it is moved out of beta. Even though it does support memory at 6000 it is unlikely I will upgrade because of settings that get changed and there chances I could get blue screens with the Windows which I am not experiencing now using 24 H2
I believe the modules are supported by motherboard because I believe XMP Lancer is A Data
I may change the memory (It will not be me changing memory I will pay a qualified person) or I may just save up over time and to switch back to AMD

Your RAM should at least run at JEDEC speeds provided by SPD, which for this kit is 4800 MT/s at 1.1V. If it can't even do that with reliability, and you've verified that it's installed correctly (which includes installing them in the correct memory slots for two-DIMM operation -- DDR5_A2 and DDR5_B2 on your motherboard), then I would just open up a support/warranty claim with your reseller or your hardware manufacturer.

If it's stable at JEDEC speeds, but not XMP, you may want to give some thought as to whether it's worth pursing.

XMP is supposed to provide an easy way to apply memory overclocking with a preset clock speed, timing, and voltage setting. If you're having to manually set clock speed, there's a good chance that other critical settings like voltage weren't set properly.

Also, just because the RAM kit is rated to run at a particular speed, doesn't mean that it will be capable of running at that speed in your particular system. RAM kits are often rated for the best-case scenario, whereas the number of memory ranks on a DIMM, as well as the DIMMs per channel and the way the electrical circuits for the memory are laid out on the motherboard can all reduce the maximum speed that the system can run at.

Also, given that the the high-end SKUs for the 13th and 14th gen Intel series (and the 14900K in particular) have experienced physical damage from the settings they run at out of the box, I don't think overclocking them further is wise.

If this is a mixed-use computer that will only be crunching when it's idle or otherwise not in-use for other interactive tasks, then I'd say try to get XMP working if you're prioritizing computing performance over efficiency and reliability.

If you're just using this computer for BOINC, I'd say it's not worth using XMP, both because it'll drop performance per watt, and because there's a good chance that it won't be entirely stable if it didn't work out-of-the-box the first time.

Re: I9–14900KF Cooling

Thanks for the feedback William.

From what you have said I am interpreting it as you saying I will not get any advantage from switching to 2 sticks of RAM as opposed to 4 like I am using currently?

Touching on my CPU briefly I purchased it after the voltage issue had been sorted in the BIOS which is BIOS F7 in my case
